Upper & Lower Broiler Flame Adjustment

I just converted my 2005 Kenmore Wall Gas Oven (790) over to LP from Natural Gas. I inverted the little plunger in the thermostat for LP, adjusted the burner orifice spud and adjusted the Air Adjustment Shutter as per instruction in the service guide. I double checked everything and followed instructions to the letter!

You have an LP gas stove which you really like and would like to take to a new home but the new home has a natural gas hookup. Since natural gas is already available it would be convenient to be able to use it. Can you convert your unit over to work on natural gas?

Yes it is possible to convert any LP gas appliance to natural gas or from natural gas to LP. The only difference is the size of the orifice used in the burner.

LP gas is composed of a much larger molecule than natural gas and requires a larger orifice to output the same amount of gas as a natural gas unit at the same setting. Therefore if you used an LP stove on natural gas it would produce too much heat and burn rather intensely. If you used a natural gas stove on LP it would not have much flame at all. You can see the problem. The solution is also obvious. You need the correct orifice.

Changing the orifice is easy. It is located in the middle of the burner and unscrews out of the unit. Install the new one the opposite way. Do not overtighten it.Usually the burners are made of soft metal and can strip easily.

The parts you would need are available at most good appliance stores but I would recommend the following site http://www.repairclinic.com . The parts will be cheaper at repairclinic. They have parts for almost any brand and a great search engine. They also have excellent videos showing how to make the repair.

Kenmore Gas ranges can be used with Natural gas or Lp. They come from the factory set up for Natural gas so if you want to use Lp it needs to be converted by you or your gas company. There are several adjustments that have to be made and some ranges require orifices to be changed. Your installation manual tells how to convert it but if you're not sure about doing it you would be better off the call the gas man.

Not really sure which model you have but when converting the over, ether bake or broil burner you tighten down the orfice cap. If you remove the burner off the oven valve you will notice that you can put a wrench on the orfice cap. Just tighten snuggly. If you over tighten you will crush the orfice under the cap.

First thing you will need to do is find out from the manufacturer of the oven if there is a conversion kit available and if the appliance is convertable. If there is then you can order the kit and follow the installation instructions. Also check the back of the oven for an envelope that may contain the gas orfice replacement heads to convert the appliance to natural gas. If you find the replacement orfice then you will need to remove the lp orfice from the burner and install the natural one. Then the appliance gas regulator will need to have the pressure adjusted lower for natural gas. There is usually a removable cap on top of the regulator on the oven. When you remove this cap there is usually a small metal ring that you can remove and flip over. It will say "nat" on one side and "lp" on the other. You will need to turn this ring over and re-insert so it displays "nat". This will change the gas pressure from 13 inches W.C. to 4 inches W.C. Some appliances only require the orfice change and no regulator adjustment but make sure that is the case with your oven because if you feed 13 inches W.C. pressure to a burner with a natural gas orfice...YOU WILL GET A HUGE BURNER FLAME AND MAY BURN/FLASH YOURSELF...So use extreme caution when converting a gas appliance. And if the oven has a pilot you will need to adjust the pilot pressure or change it's orfice if it has one. If it is electronic ignition no adjustment to that will be needed. Also unplug the electrical power the the unit while working on it.
